Question

Find the area of the following quadrilaterals:


plz solve this​

Answer 1

Answer:

These is a Rectangle

So , Area of rectangle = Length • Breadth

In these rectangle

Area of rectangle(PQRS) =

Length (PQ) • Breadth (PS)

So, in triangle ∆SNR ,

SN = 30 cm , NR = 10 cm , SR = ?

By pythagorus equation,

SR = √(SN)2 + (NR) 2

we get SR =√1000

= 10√ 10 cm

SR=PQ=10√10 cm
